To all whom it may concern:

Be it known that I, JoHvAT -IA'N A. DIG-KEY, a citizen of the United States, residing at C0- lumbus, in the. county of Bartholomew and Stat-e of Ind.iana,-have invented a new and useful Lubricator for Steam-Engines, of which the following is a specification.

This invention relates to lubricators for steam andhydrocarbon engines and the like and is moreparticularly designed for use where the lubricant is to be forced against pressure within the engine. The object of the invention is to provide simple and efficient means whereby a lubricant can bewithdrawn in predetermined quantities and at predetermined eriods from i a receptacle and subsequently orced to the point of use.

' Referring to the' drawing by characters of reference, 1 'designates an oil rece tacle which may be of any suitable size an proportion and preferably provided wit a I of, while a sight glass 4of suitable construc-. tion is arranged along one side of the recep tacle. .A shaft 6 'extends from one wall of --'the receptacle 1v and .revoliibly mounted thereon is a ratchet wheel 7 and an eccentric 8 rotating therewith. This eccentric is disposed to actuate a itman 9 connected to a, plun 'er 10 mounte, to reciprocate within atubular casing 11 located within the recepta- 6 cle and provided'with an oil inlet port 12. An outlet port'13- extends from the casing 11 at a point below the port 12 and this outlet port is normally closed. by meansof a check.

valve 14 which as shown in the dra may 0 consist of a spring'pressed ball 15. A tubular screw plu 16 may be utilized for hol the valve in lace, and said plug also coiit i tutes means or connecting a discharge pipe to the 'lubricator. The bottom portion of the bore of casing 11 is enlarged as at 17 to Another object is to provide simple and form an interior annular shoulder-.18 and the screw plug 19 is detachably mounted within the lower end of said bore and serves to-suport a cushioning spring 20. This spring liears against a washer 21 which is secured to the lower end of a plunger 22 and is held normally in contact with the shoulder 18 by the spring 20. Plunger-22 normally extends a short distance above the port 13 so that when the plunger is raised an oil receiving compartment 23 is formed therebetween and the ort 12 opens into it. A suitable drain 24 s preferably located 11 on the bottom of the receptacle 1 so. that t e same can be cleaned out whenever desired.

An arm 25 isfulcrumed upon the shaft 6 and'pivoted thereon is a casing 26 in which is located a spring ressed pawl 26 normally engaging the rate et wheel 7. The pivotal movement ofthe casing .26 is limited b means of a stop 27 and a screw 28 which -1s Patented Karen a, 1908'.

mounted in a support 29 provided-therefor.

Both the stop an support 29 are arranged in the arm. A s ring 30 is mounted close to and is dispose to engage the ratchet wheelso as to rection. 1

It is to be understood that the arm 25 is to be connected to a movable plart of an. engine so that said arm will be osc ated during the operation of the engine. When the plungers are in the position shown inthe drawing oil prevent it from rotating in one diwill be free to flow through port 12 and. into compartment 23. Asthe arm 25 oscillates .6 straineri2 and a screw cap 3 at'the-top therebackward and forward it slowly revolves the ratchetwheel 7 and eccentric 8 and gradually moves the plunger 10 downward. Said plunger forces the oil which is within the com artment 23- against the spring supportv ed unger 22. and immediate subsequent to t 0 closing of port 12 by p unger 10 the pressure on the (plunger 22 causes the same to move downwar and open the port 13. The oil will therefore be forced outward-through said opening b spring 20 andwill and, to the oint of use.'

will be slowl raised and as sooii as it passes the'port 12 t e oil will flow into the comdpartment 23 and fill the vacuum pro uced therein.

the pressure exerted-by be directed ast the ball 15' I the ratchet .Eheel 7 continues'to rotate the plunger 10 It will be obvious that by adjusting screw 28 the backward movement of the casing 26 i and pawl 26 can be increased or diminished events so as to slip over one or more teeth and correspondingly inerease or diminish the feed of oil. if desired the mechanism can be quickly actuated manually. To do this a grip or crank 31 is placed upon the ratchet 7 so that the operator can readily rotate said ratchet. it will be seen that the apparatus is very simple, durable, and etlieient, and will ell'eetually operate to supply lubricant to wheel, means operated thereby for reciproeating the plunger, an oscillatory arm, a pawl carried thereby and engaging the ratchet. wheel, and adjustable detachable means for limiting the movement of the pawl.
